TLS cert key collision: duplicate checks for shared IP + SNI targets #56

Cert state key is ip:port:hostname. If the same IP serves different certs for different SNI hostnames (SNI routing), this works. But if two configured hostnames share the same IP AND the same SNI target (e.g. CNAME to CDN), we get duplicate checks.

Minor inefficiency, not a correctness bug.
